Your genes are not your medical destiny.
Dr. David Katz
With relatively uncommon exception, that is the rule established by ground-breaking research published over recent years, and nicely illustrated by a 2008 paper in the Proceedings of the National Academy of Sciences. That rule could, and perhaps should, remake the way you play the game of life.
The illustrative trial was a pilot study of 30 men with early stage prostate cancer who were eligible to be observed carefully for disease progression without undergoing surgery, radiation or chemotherapy. These men were enrolled into a trial called GEMINAL, developed and implemented by my friend, Dr. Dean Ornish, and his colleagues at the University of California, San Francisco.
The study took advantage of often indolent prostate cancer to assess the effects of a lifestyle intervention, without the confounding influences of medical or surgical cancer treatments. The men participating in the GEMINAL study received a lifestyle intervention: low-fat, whole foods, plant-based nutrition; stress management techniques; moderate exercise; and participation in a psychosocial support group. The study lasted three months. Continue reading
Coffee lovers are likely enjoying a new study finding that coffee lowers risk for endometrial cancer, with the drink being almost the lone dietary factor linked to risk. The study was a large one and it’s coffee findings are similar to those of AICR’s report released last year.
That’s certainly good news for coffee lovers, but whether you do or don’t enjoy coffee, the beverage is only one of several ways you can protect yourself against endometrial cancer.
The study, published in this month’s Cancer Epidemiology, Biomarkers & Prevention, looked at 84 foods and/or nutrients related to endometrial cancer risk. Study researchers first investigated the link among about 300,000 women participants of the European Prospective Investigation into Cancer and Nutrition (EPIC). Women had filled out questionnaires about what they ate and other lifestyle habits, and then they were tracked for endometrial diagnosis or death. This led to 10 factors linked to either increased or decreased risk, including coffee, total fat, butter, and cheese.
Then the researchers looked at how these factors linked to 155,000 women who were in two US studies, the Nurses’ Health Studies I and II. These women had also had answered questions about diet and other factors. Continue reading
AICR recommends choosing whole grains over refined or processed grains— in addition to being higher in nutrients and phytochemicals, whole grains contain more fiber than refined grains. Foods containing fiber protect against colorectal cancer and may keep you full longer, helping you manage your weight. Whole grains are also linked to a lower risk of heart disease and type 2 diabetes.
Scientists are not sure why whole grains and fiber are beneficial for health, but a new study in mice published in the Journal of Nutrition adds to the evidence that changes in the types of bacteria that live in the intestines—known as the gut microbiota—may be important.
The researchers fed one group of mice flour made from whole grain oats, while the other group of mice got refined flour lower in soluble fiber. Soluble fiber slows the passage of food through the digestive tract, which may help keep you feeling full longer. It is also linked to lower cholesterol and increased insulin sensitivity, important factors in the development of heart disease and type 2 diabetes.
Both diets had the same amount of protein, carbohydrate, fat, and insoluble fiber. Continue reading
